Question

Displacement versus time curve for a particle executing SHM is shown in figure. Choose the correct statements.

A. (a) Phase of the oscillator is same at `t=0"s and t"=2s`
B. Phase of the oscillator is same at `t=2s" and "t =6s`
C. Phase of the oscillator is same at `t=1s"and " t=7s`
D. Phase of the oscillator is same at `t=1s"and " t=5s`

Answer 1

It is clear from the curve that points corresponding to `t=2s" and "t=6s` are separted by a distance belongs to one time period. Hence, these points must be in same phase.

Similarly, points belong to `t=1s" and "t=5s` are at separation of one time period, hence must be in phase.
